Integral safety carrying method on the sea for wind power generator set

Abstract

The invention relates to a method for integrally and safely conveying a wind turbine on the sea which includes the following steps: 1) the wind turbine comprising a tower drum and an internal electric device is assembled into an integral body; 2) the wind turbine is hoisted on a deck by a hoisting ship and the bottom part of the wind turbine is welded and fixed on the deck; 3) a measuring ship is adopted to monitor the wave height, the wind speed and the wind direction; 4) a gyroscope moving instrument is fixed and a rolling angle, a pitching angle, the acceleration of the rolling angle and the acceleration of the pitching angle are measured; 5) an acceleration sensor is arranged and the transverse acceleration and the longitudinal acceleration of the upper part of the tower drum are measured; 6) strain foils are arranged at the circumference direction at the centralized location of the strain and the load data at the locations of each strain foil is obtained by a conventional electrometric method; 7) the data information obtained from step 3) to step 6) are integrated and control is carried out on the sail or sail suspending, course and sail speed of a transport barge; 8) the wind turbine is wholly cut from the deck and wholly hoisted on a foundation pre-manufactured on a marine mounting part. The method has very important practical meanings on the development and construction for a large scale marine wind farm.

Description

technical field [0001] The invention relates to a method for safe transportation at sea, in particular to a method for safe transportation of wind turbines as a whole at sea. Background technique [0002] Wind energy plays a dominant role in the development of renewable energy, and 13 countries around the world have installed capacity exceeding 1 million kilowatts. Offshore wind energy has unique advantages such as not occupying land resources, being far away from crowds, and causing little interference to social life. With the continuous maturity of technology, offshore wind energy will become an important part of future green energy, but my country's current wind power generation business is still in its infancy, and offshore wind power generation is still blank. The overall transportation and installation of offshore wind turbines includes many technical and engineering links, among which the overall offshore transportation and hoisting of wind turbines is one of the mos...

AI Technical Summary

Problems solved by technology

However, the offshore assembly period is relatively long, and there are many uncontrollable factors. If encountering severe weather and environmental conditions, the construction period will be longer and the difficulty will increase, which will result in a substantial increase in cost; 2. For wind farms where the construction site is relatively close to the land In this situation, the whole wind turbine unit is hoisted and transported by a double pole transport ship, and the wind turbine unit is not fixed on the deck. Due to the short transportation distance, the interference factors of wind, waves and ocean currents have little influence
